408 Mr. A. G. Butler on new Genera 



liformis^ Walker, I. c. p. 16. n. 7, as a synonym of JE. antlira- 

 ciformis of llambur. 



JE. phckrformis and jE. einphytiformis of Walker appear 

 to me to be better placed in the genus Tarsa^ the antenna? 

 being much more pectinated than in the other species of the 

 genus. 



^. trypTioniformiSy yE". plectisctformis^ and ^E'. iscliniformis 

 (all from Para only) are identical. 



jE. porizomfonnis comes only from Pard ; specimens 

 quoted from Tapajos and Villa Nova are referable to distinct 

 species. 



^. panurgiformis occurs at Santarem, Tapajos, and Villa 

 Nova, but not at Par^, specimens quoted from the latter 

 locality being referable to distinct species. 



u^. leiceformis may be referred to the genus Tinthia of 

 Walker. 



yE. cryptiformis might be placed in Sannina of Walker, of 

 which A^. exitiosa, Say [uroceriformis, Walk.), is the type. 



zE. crassicorms, Walker, Lep. Het. Suppl. i. p. 7 (1864), 

 would be better placed in Smcara of Walker ; it differs, how- 

 ever, from the type, in its tufted hind legs, which (unless a 

 sexual character) would entitle it to be ranked as the type of 

 a new genus. 



u^. cupreipennis would be better placed in Tinthia, with 

 which it agrees structurally. 



u:E. gravis and jE. hicincta are referable to the section 

 Sciapteron, considered by Staudinger to be a distinct genus.
